What is a .docm file?
A .docm file is a Macro enabled Microsoft Word Document OOXML (version 2007 Onwards). This is a document format, so it holds text and layout meant to be read.
How to open a .docm file
- Try LibreOffice (free, Windows/Mac/Linux) — it opens an enormous range of current and historic document formats.
- Microsoft Word and Google Docs handle most mainstream document types.
- If nothing opens it, open it in a text editor: many older document formats have readable text inside.
The registry records this extension against Macro enabled Microsoft Word Document OOXML, so software from that family is the most likely match.
How to convert a .docm file
- Once it opens in LibreOffice or Word, Save As .docx or .pdf to get it into a format you can use anywhere.
